DETAILED DESCRIPTION

In the following detailed description, reference is made to the accompanying drawings, which form a part hereof. In the drawings, similar symbols typically identify similar components, unless context dictates otherwise. The illustrative embodiments described in the detailed description, drawings, and claims are not meant to be limiting. Other embodiments may be utilized, and other changes may be made, without departing from the spirit or scope of the subject matter presented here.

In some situations, the performance and/or operation of a stretchable electronic device worn on the body depends in part on the specific orientation and position of the stretchable electronic device on the surface of the body part relative to one or more features underlying the surface of the body part. For example, in some embodiments, a stretchable electronic device is placed on a body part in order to monitor an internal condition of the body, such as blood pressure, pulse, nerve activity, muscle activity, and/or motion of internal structures. Precise positioning and orientation of the stretchable electronic device can improve the ability of the device to carry out this monitoring. See, e.g., Jeong et al., “Materials and Optimized Designs for Human-Machine Interfaces Via Epidermal Electronics,” Advanced Materials 25: 6839-6846 (2013), which is incorporated by reference. For example, a stretchable electronic device can include a sensor of electrical activity at a specific location on the electronic device, and position of that sensor adjacent to a subsurface nerve can improve the detection of electrical activity in that particular nerve. For example, a stretchable electronic device can include an antenna and be configured to accept signals from an implanted medical device within a body, and to relay the received signals from the implant to an external device distal to the body. The position and orientation of the stretchable electronic device and its antenna can, in some situations, impact the functionality of the antenna and the relay of signals from the implant to an external device distal to the body. Similarly, a stretchable electronic device can include an inductive coil and be positioned and oriented to provide power to an implant located in a subsurface position in a body. For example, a stretchable electronic device can include a heater and a thermocouple, and the stretchable electronic device can be configured to detect temperature of the object and then to deliver heat to the object. For example, a stretchable electronic device can include an RFID tag which is intended to be placed at a position or orientation relative to the object. Devices and methods described herein can be used to assist with the positioning and orientation of one or more stretchable electronic devices during application to a surface of a body relative to subsurface features.

In some situations, the performance and/or operation of a stretchable electronic device affixed to a surface of an inanimate object depends in part on the specific orientation and position of the stretchable electronic device on the surface of the inanimate object relative to one or more features underlying the surface of the inanimate object. For example, in some embodiments, a stretchable electronic device is placed on an inanimate object in order to monitor an internal condition of the inanimate object, such as electrical activity, magnetic activity, sound, internal motion, and/or structural integrity of material. Precise positioning and orientation of the stretchable electronic device can improve the ability of the device to carry out this monitoring. For example, a stretchable electronic device can include a motion sensor, and positioning of the motion sensor adjacent to a motor within the inanimate object can improve detection of motion of the motor. For example, a stretchable electronic device can include an electrical sensor, and positioning of the electrical sensor adjacent to an electrical conduit within the inanimate object can improve detection of electrical signals from the conduit. For example, a stretchable electronic device can include a thermocouple or a radiator, and the stretchable electronic device can be configured to detect heat and then to disperse the heat along the surface of the object or transfer it to external air. The position and orientation of the thermocouple or radiator can, in some situations, alter the ability of the stretchable electronic device to detect and disperse heat along the surface of the object. Devices and methods described herein can be used to assist with the positioning and orientation of one or more stretchable electronic devices during application to a surface of an inanimate object relative to subsurface features.

With reference now to FIG. 1, shown is an example of a stretchable electronic device affixed to a human wrist that may serve as a context for introducing one or more processes and/or devices described herein. The use of the same symbols in different drawings typically indicates similar or identical items unless context dictates otherwise. Aspects of the figures are portrayed for purposes of illustration, and accordingly may not be drawn to scale. FIG. 1 depicts an embodiment wherein a stretchable electronic device is applied to a specific location on a surface, and orientation on the surface, relative to the underlying features underneath that specific surface. FIG. 1 depicts a stretchable electronic device affixed to a human wrist relative to, inter alia, the blood vessels underlying the skin surface of the wrist. Although a particular configuration of blood vessels is illustrated in FIG. 1, the precise positioning of blood vessels in a particular human wrist varies between individuals. The features of a human body underlying the surface, such as blood vessel position, may be partially visible or not visible, depending on the individual person and their position at a particular time. In addition, other features of a human body underlying the skin layer will vary between individuals, such as the size of a body part, the curvature and surface of the body part, and the composition and precise position of the underlying features of the body part. Therefore, the exact positioning and orientation of a stretchable electronic device will vary between individuals.

Some embodiments of the devices and methods are suitable for use to apply a stretchable electronic device to the surface of an inanimate object, the stretchable electronic device positioned and oriented relative to underlying features of the surface. For example, in some embodiments a stretchable electronic device can be applied to a surface of another device relative to features such as cracks, voids or gaps in the structure underlying the surface, anticipated stress concentration sites, electric connections under the surface, motors within the inanimate object, or other features within the inanimate object. Therefore, the exact positioning and orientation of a stretchable electronic device relative to features under the surface can vary between specific inanimate objects that are otherwise similar.

Some embodiments of the devices and methods are suitable for use to apply a stretchable electronic device to the surface of a plant, the stretchable electronic device positioned and oriented relative to underlying features of the surface. For example, in some embodiments a stretchable electronic device can be applied to a surface of a plant relative to features such as pores, internal channels, internal cavities, buds, branch points, or other features within the plant. Therefore, the exact positioning and orientation of a stretchable electronic device relative to features under the surface can vary between specific plants that are otherwise similar.

FIG. 1 illustrates a human hand 120 and wrist 130 regions of a body. The wrist 130 includes a region of interest 140 which includes a plurality of blood vessels 145 under the skin, and adjacent to the skin layer. Although blood vessels 145 are illustrated in FIG. 1, similarly situated blood vessels may or may not be visible in a given individual depending on factors such as skin thickness and pigmentation of an individual. A stretchable electronic device 100 is affixed to the wrist 130 in the region of interest 140. In some embodiments, the stretchable electronic device can be of a type and positioned to monitor different aspects of the underlying features of the adjacent surface. For example, in embodiments wherein a stretchable electronic device is affixed to a surface of a body part, the stretchable electronic device may be positioned and oriented relative to features under the surface such as blood vessels, nerves, bones, fat deposits, muscle groups, skin layer thickness and composition, and prior surgical implants. The features under the surface may not be visible to a user. See, e.g. Swisher et al., “Impedance Sensing Device Enables Early Detection of Pressure Ulcers in Vivo”, Nature Communications, 6: 6575, doi: 10/1038.ncomms7575, which is incorporated herein by reference. In addition, a stretchable electronic device can be positioned and oriented relative to features that are included at the surface level, such as scar tissue, wrinkles, tattoos, pigmented regions, neoplastic regions, and wear regions. Features that are included at the surface level may not be easily visible to a user. A stretchable electronic device can also be positioned and oriented on a body part relative to cosmetic or comfort desires of the wearer.

A “stretchable electronic device,” as used herein, includes a flexible and stretchable substrate and attached electronic circuitry, the device fabricated as an extremely thin structure of a size and shape to conform with a surface of an object for a period of time, such as days or weeks. In some embodiments, a stretchable electronic device has a thickness on in the μm scale, and has a low Young's modulus, on the kPa scale (see, e.g. Kim et al., “Epidermal Electronics,” Science 333: 838-843, (2011), which is incorporated herein by reference). For example, in some embodiments a stretchable electronic device has an average thickness less than 100 μm, and an average Young's modulus less than 100 kPa. For example, in some embodiments a stretchable electronic device has an average thickness less than 50 μm, and an average Young's modulus less than 80 kPa. For example, in some embodiments a stretchable electronic device has an average thickness less than 500 microns, and an average modulus less than or equal to 500 kPa (see, e.g. US Patent Application Publication No. 2013/0041235, “Flexible and Stretchable Electronic Systems for Epidermal Electronics, to Rodgers and Kim, which is incorporated herein by reference). In some embodiments, a stretchable electronic device can be an epidermal electronic device (see, e.g. Kim et al., “Epidermal Electronics,” Science 333: 838-843, (2011), and Ma, “An Electronic Second Skin,” Science 333: 830-831, (2011), which are each incorporated herein by reference). In some embodiments, a stretchable electronic device can be a conformal electronic device. In some embodiments, a stretchable electronic device includes a support fabricated from silk fibroin (see, e.g. Kim et al., “Dissolvable Films of Silk Fibroin for Ultrathin, Conformal Bio-Integrated Electronics,” Nature Materials 9(6): 511-517 (2010), which is incorporated herein by reference). Some embodiments include a stretchable electronic device from a support, which can include a support that is peeled off or dissolved away after application of the stretchable electronic device to the surface (see, e.g.: Yeo et al., “Multifunctional Epidermal Electronics Printed Directly Onto the Skin,” Advanced Materials (2013), DOI: 10.1002/adma.201204426; US Patent Application Publication No. 2012/0157804, “High-speed, High-resolution Electrophysiology In-vivo Using Conformal Electronics” to Rogers et al.; Salvatore et al., “Wafer-scale Design of Lightweight and Transparent Electronics that Wraps Around Hairs,” Nature Communications (2014) DOI: 10.1038/ncomms3982; and US Patent Application Publication No. 2013/0041235, “Flexible and Stretchable Electronic Systems for Epidermal Electronics, to Rodgers and Kim, which are each incorporated herein by reference). Some embodiments include a stretchable electronic device including a barrier layer. The barrier layer of a stretchable electronic device can include patterns to modulate contact between one or more features of the stretchable electronic device and a surface affixed to the stretchable electronic device (see, e.g., US Patent Application Publication No. 2012/0157804, “High-speed, High-resolution Electrophysiology In-vivo Using Conformal Electronics” to Rogers et al., which is incorporated herein by reference).

A stretchable electronic device can include a plurality of inflexible blocks, sometimes referred to as device islands, each affixed to a support and integrated into a stretchable electronic device (see, e.g.: US Patent Application Publication No. 2013/0041235, “Flexible and Stretchable Electronic Systems for Epidermal Electronics, to Rodgers; U.S. Pat. No. 8,536,667, “Systems, Methods and Devices Having Stretchable Integrated Circuitry for Sensing and Delivering Therapy,” to de Graff et al; U.S. Pat. No. 8,097,926, “Systems, Methods and Devices Having Stretchable Integrated Circuitry for Sensing and Delivering Therapy,” to de Graff et al; and Kim, and Kim et al., “Materials for Stretchable Electronics in Bioinspired and Biointegrated Devices,” MRS Bulletin 37: 226-235 (2012), which are each incorporated herein by reference). In some embodiments, each of the inflexible blocks includes a functional unit. For example, a functional unit can include a temperature sensor, a pressure sensor, an accelerometer, antenna, receiver, transmitter, electrical sensor, magnetic sensor, tension sensor, processor, energy harvesting device, circuitry to any of the functional units, or other functional component. The inflexible blocks including functional units can be connected to each other by wire connectors to create electrical circuitry system throughout the stretchable electronic device. The inflexible blocks including functional units can be connected to each other by wireless connectors to create electrical circuitry system throughout the stretchable electronic device. See, e.g. US Patent Application Publication No. 2011/0054583, “Flexible and Scalable Sensor Arrays for Recording and Modulating Physiologic Activity,” to Litt and Viventi, which is incorporated herein by reference. In some embodiments, a stretchable electronic device can be fabricated by use of a stamp (see, e.g.: US Patent Application Publication No. 2007/0142619, “Forming Electrical Contacts to a Molecular Layer,” to Hsu et al.; and U.S. Pat. No. 8,372,726, “Methods and Applications of Non-planar Imaging Arrays,” to de Graff et al., which are each incorporated herein by reference).

In some embodiments, a stretchable electronic device can be fabricated with a silicon wafer substrate (see, e.g., Hwang et al., “Materials and Fabrication Processes for Transient and Bioresorbable High-performance Electronics,” Advanced Materials (2013), DOI: 10.1002/adfm.201300127, which is incorporated herein by reference). In some embodiments, a stretchable electronic device can be fabricated to include bioresorbable radio frequency electronics (see, e.g, Hwang et al., “Materials for Bioresorbable Radio Frequency Electronics,” Advanced Materials (2013), DOI: 10.1002/adma.201300920, which is incorporated herein by reference).

A “user,” as used herein, is a person applying a stretchable electronic device to a surface. In embodiments wherein the stretchable electronic device is applied to the surface of a body part (e.g. the skin or epithelial tissue), the user can include a medical team member applying the stretchable electronic device. In some embodiments, devices and methods as described herein can be used by an individual to apply a stretchable electronic device to their own body surface(s) relative to features underlying the surface, and a “user” can include the individual. In some embodiments, a stretchable electronic device is applied to the surface of an inanimate object, and the user is the person who carries out the application relative to features underlying the surface of the object. Depending on the embodiment, a user can be representative of a human user, a robotic user (e.g., computational entity), and/or substantially any combination thereof (e.g., a user may be assisted by one or more robotic agents) unless context dictates otherwise.

FIG. 2 illustrates additional aspects of a stretchable electronic device 100 applied to the skin surface of a wrist 130 relative to features underlying the skin surface. The stretchable electronic device 100 applied to the skin surface of a wrist 130 in a position and orientation for best results of the stretchable electronic device 100. The wrist 130 includes a region of interest 140 which includes a plurality of blood vessels 145 under the skin. The stretchable electronic device 100 depicted in FIG. 2 has been applied so that the stretchable electronic device 100 is positioned and oriented to maximize operability of the stretchable electronic device 100. The stretchable electronic device 100 depicted in FIG. 2 has been applied so that the stretchable electronic device 100 is positioned and oriented to place two functional units 200 of the stretchable electronic device 100 on the surface of the wrist 130 at positions adjacent to underlying blood vessels 145. Depending on the embodiment, the two functional units 200 can be of one or more types that are the same as each other, or different from each other. The two functional units 200 of the stretchable electronic device 100 positioned on the skin surface adjacent to the underlying blood vessels 145 are of a type that operate more efficiently, and/or with better results, when positioned on a surface adjacent to an underlying blood vessel. For example, the functional units could include, in some embodiments, a pressure sensor configured to monitor blood pressure or pulse rate, and/or a light emitter and receiver configured for pulse oximetry. The stretchable electronic device 100 has been positioned and oriented relative to its major axes, identified as X and Y in FIG. 2. A third functional unit 210 of the stretchable electronic device 100 is not in a position adjacent to a blood vessel 145. The third functional unit can be of a type that does not operate more efficiently, and/or with better results, when positioned on a surface adjacent to an underlying blood vessel. For example, the third functional unit could include, depending on the embodiment, an antenna, a receiver, a transmitter, an energy harvesting device, or circuitry relating to another functional unit. In some embodiments, a stretchable electronic device can be positioned and oriented based on a combination of features of a body underlying the surface as well as those at the surface level (e.g. scars, wrinkles, pigmentation areas, neoplasias, etc.). In some embodiments, a stretchable electronic device includes a barrier layer that creates regions of higher and lower contact of functional units of the stretchable electronic device with an affixed surface. In some embodiments, a stretchable electronic device can be positioned and oriented on a surface of an object by a positional applicator device relative to the barrier layer of the stretchable electronic device, one or more functional units of the stretchable electronic device, and subsurface features of the object.

FIG. 3 depicts aspects of a stretchable electronic device 100 applied to the skin surface of a wrist 130. The stretchable electronic device 100 depicted has not been applied to the skin surface of the wrist 130 in a position and orientation to maximize operability of the stretchable electronic device 100. The stretchable electronic device 100 depicted in FIG. 3 has been applied so that the stretchable electronic device 100 is positioned and oriented to place all of the functional units 200, 210 of the stretchable electronic device 100 on the surface of the wrist 130 at positions that are not adjacent to underlying blood vessels 145. The stretchable electronic device 100 has been positioned and oriented relative to its major axes, identified as X and Yin FIG. 3. Assuming that two of the functional units 200 of the stretchable electronic device 100 are of type that operate with maximum efficiency when they are placed on a skin surface adjacent to the blood vessels under the skin surface of the wrist, the position and orientation of the stretchable electronic device 100 shown in FIG. 3 does not promote maximum efficiency of the stretchable electronic device 100 for at least those functional units.

FIG. 4 depicts an inanimate object 400 with a stretchable electronic device 100 affixed to the surface of a region of interest 140 of the inanimate object 400. The stretchable electronic device 100 is oriented on the surface of the region of interest 140 of the inanimate object 400 relative to its major axes, identified as X and Y in FIG. 4.

The state of the art has progressed to the point where there is little distinction left between hardware, software (e.g., a high-level computer program serving as a hardware specification), and/or firmware implementations of aspects of systems; the use of hardware, software, and/or firmware is generally (but not always, in that in certain contexts the choice between hardware and software can become significant) a design choice representing cost vs. efficiency tradeoffs. There are various vehicles by which portions of the processes and/or systems and/or other technologies described herein can be effected (e.g., hardware, software (e.g., a high-level computer program serving as a hardware specification), and/or firmware), and that the preferred vehicle will vary with the context in which the processes and/or systems and/or other technologies are deployed. For example, if an implementer determines that speed and accuracy are paramount, the implementer may opt for a mainly hardware and/or firmware vehicle; alternatively, if flexibility is paramount, the implementer may opt for a mainly software (e.g., a high-level computer program serving as a hardware specification) implementation; or, yet again alternatively, the implementer may opt for some combination of hardware, software (e.g., a high-level computer program serving as a hardware specification), and/or firmware in one or more machines, compositions of matter, and articles of manufacture. Hence, there are several possible vehicles by which the processes and/or devices and/or other technologies described herein may be effected, none of which is inherently superior to the other in that any vehicle to be utilized is a choice dependent upon the context in which the vehicle will be deployed and the specific concerns (e.g., speed, flexibility, or predictability) of the implementer, any of which may vary. Optical aspects of implementations will typically employ optically-oriented hardware, software (e.g., a high-level computer program serving as a hardware specification), and or firmware.

In some implementations described herein, logic and similar implementations may include computer programs or other control structures. Electronic circuitry, for example, may have one or more paths of electrical current constructed and arranged to implement various functions as described herein. In some implementations, one or more media may be configured to bear a device-detectable implementation when such media hold or transmit device detectable instructions operable to perform as described herein. In some variants, for example, implementations may include an update or modification of existing software (e.g., a high-level computer program serving as a hardware specification) or firmware, or of gate arrays or programmable hardware, such as by performing a reception of or a transmission of one or more instructions in relation to one or more operations described herein. Alternatively or additionally, in some variants, an implementation may include special-purpose hardware, software (e.g., a high-level computer program serving as a hardware specification), firmware components, and/or general-purpose components executing or otherwise invoking special-purpose components. Specifications or other implementations may be transmitted by one or more instances of tangible transmission media as described herein, optionally by packet transmission or otherwise by passing through distributed media at various times.

Alternatively or additionally, implementations may include executing a special-purpose instruction sequence or invoking circuitry for enabling, triggering, coordinating, requesting, or otherwise causing one or more occurrences of virtually any functional operation described herein. In some variants, operational or other logical descriptions herein may be expressed as source code and compiled or otherwise invoked as an executable instruction sequence. In some contexts, for example, implementations may be provided, in whole or in part, by source code, such as C++, or other code sequences. In other implementations, source or other code implementation, using commercially available and/or techniques in the art, may be compiled//implemented/translated/converted into a high-level descriptor language (e.g., initially implementing described technologies in C or C++ programming language and thereafter converting the programming language implementation into a logic-synthesizable language implementation, a hardware description language implementation, a hardware design simulation implementation, and/or other such similar mode(s) of expression). For example, some or all of a logical expression (e.g., computer programming language implementation) may be manifested as a Verilog-type hardware description (e.g., via Hardware Description Language (HDL) and/or Very High Speed Integrated Circuit Hardware Descriptor Language (VHDL)) or other circuitry model which may then be used to create a physical implementation having hardware (e.g., an Application Specific Integrated Circuit).

In a general sense, various embodiments described herein can be implemented, individually and/or collectively, by various types of electro-mechanical systems having a wide range of electrical components such as hardware, software (e.g., a high-level computer program serving as a hardware specification), firmware, and/or virtually any combination thereof; and a wide range of components that may impart mechanical force or motion such as rigid bodies, spring or torsional bodies, hydraulics, electro-magnetically actuated devices, and/or virtually any combination thereof.
